iphone - UItableView删除行使用函数

Question

我有 NSMutableArray“day”，其中包含(6 个 NSMutable 数组)数组包含

class Lesson{
    NSString *time1;
    NSString *time2;
    NSString *predmet;
    NSString *namPrepod;
    NSString *zamet;
}

我有获取当前周、日、课的功能

-(Lesson *)lessonInWeek:(int)week inDay:(int)day lessonNumber:(int)lNumber
{
    Week *currentWeek = nil;
    if(week)    
        currentWeek = nechetNedel;
    else        
        currentWeek = chetNedel;

    NSMutableArray *dayArray = [currentWeek.days objectAtIndex:day];
    Lesson *lesson = [dayArray objectAtIndex:lNumber];

    return lesson;
}

用这个函数我展示在

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
......
 Lesson *item = [[Singleton sharedInstance] lessonInWeek:segmentedControl.selectedSegmentIndex inDay:indexPath.section lessonNumber:indexPath.row];

    ....
    time1.text= item.time1;
    ....

    time2.text= item.time2;
    ....
    predmet.text=item.predmet;
    .....
    namePrepod.text=item.namPrepod;
    ......
    zamet.text=item.zamet;
    ....

谁可以在不使用 的情况下使用此功能删除行？

if(segmentedControl.selectedSegmentIndex==0)
if(section==1)
......

删除一行需要编辑的函数。

将 deleteLessonInWeek:inDay:lessonNumber: 添加到您的单例类中，并从您的 tableView:commitEditingStyle:forRowAtIndexPath: 实现中调用它:

- (void) tableView:(UITableView*)tableView
    commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
    forRowAtIndexPath:(NSIndexPath*)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [[Singleton sharedInstance] deleteLessonInWeek:segmentedControl.selectedSegmentIndex inDay:indexPath.section lessonNumber:indexPath.row];
    }
}

Singleton 中的实现可以使用查找日期数组的相同简洁模式，然后是一天中的类(class)，然后删除请求的项目:

-(void)deleteLessonInWeek:(int)week inDay:(int)day lessonNumber:(int)lNumber {
    // Choose odd or even week:
    Week *currentWeek = week ? nechetNedel : chetNedel;
    NSMutableArray *dayArray = [currentWeek.days objectAtIndex:day];
    [dayArray removeObjectAtIndex:lNumber];
}
